Over the last three evenings, kala received a total of 131 phone calls at the call center. the third evening, she received 4 times as many calls as the first evening. the second evening, she received 5 more calls than the first evening. how many phone calls did she receive each evening?

The no.of call received on the first evening  = 21

The no.of call received on the second evening  = 26

The no.of call received on the third evening = 84

Step-by-step explanation:

Let the no.of call received on the first evening be x.

The no.of call received on the second evening  = x + 5

The no.of call received on the third evening = 4x

x +   x+5   +  4x   = 131

6x + 5 = 131

     6x = 131 - 5

     6x = 126

        x = 126/6

       x = 21

The no.of call received on the first evening  = 21

The no.of call received on the second evening  = 21 + 5 = 26

The no.of call received on the third evening = 4*21 = 84
